Technological Solutions for Water Sustainability: Challenges and Prospects: Towards a Water-secure India
This book provides an overview of technical sustainable water management in the Global South, mainly in India, and is structured in five sections:
The current status and challenges for sustainable water management in India
New-age materials for water and wastewater treatment
New technologies for water and wastewater treatment
Sensors for water quality monitoring
Urban water management
Section 1 provides the latest information about the status and challenges for sustainable water management in India from the perspective of water quality, industrial and domestic wastewater treatment, urban water infrastructure and policy and governance towards water security. Section 2 discusses new framework solids for water purification, new materials for arsenic and fluoride removal, nanocomposites for water and wastewater treatment and removal of hazardous materials, and toxicity of these materials. Section 3 presents the new technologies developed for water and wastewater treatment; dealing with pulsed power technology, constructed wetlands, nutrient recovery, low-cost filters and pollution abatement using waste derived materials. Section 4 focuses on sensors, including the development of low-cost colorimetric sensors for eutrophying ions, sensors for conductivity and flow parameters, and multi-analyte assessment for water quality. Finally, Section 5 addresses the issues related to urban water infrastructure, sustainable urban drainage and integrated flood and water scarcity management.
This section also discusses virtual water.
The unique feature of this edited volume is its special perspective on emerging economies in the Global South, such as India. It provides information about adaption of technologies, development of new technologies, and management practices which are context driven and region specific. It also deals with economical and easy to use sensors for large-scale monitoring of water quality and water quantity parameters.

Water is an integral component of several sustainable development goals: SDG-2 (zero hunger); SDG-6 (clean water and sanitation); SDG-11 (sustainable cities and communities) and SDG-12 (responsible consumption and production). It is used in four major sectors: agricultural; domestic; industrial and ecological, and these needs could often be conflicting with each other. Further, there is a significant temporal and spatial variation in the availability of fresh water in India and in many countries in the Global South. Many countries in the Global South are already facing a major water crisis due to stressors such as increasing population and climate change, among others. Therefore, it is important to manage the scarcely available water in a sustainable way to not only meet the present needs, but also the needs of future generations. In this chapter, we briefly discuss the impending water crisis in India and other nations in the Global South and how to achieve water sustainability, both in urban and rural areas. We discuss index-based methods for measuring sustainability. We also discuss the challenges to achieve water sustainability and the way forward.
